## 📄 Fresh Masking Makes NTT Pipelines Composable: Machine-Checked Proofs for Arithmetic Masking in PQC Hardware ✍️ Ray Iskander, Khaled Kirah 🏛️ arXiv · 📅 2026-04-22 --- This paper gives machine-checked proofs for arithmetic masking properties in post-quantum cryptography hardware, focusing on NTT pipelines used in ML-KEM and ML-DSA accelerators. The core result is that fresh per-stage masking is sufficient to preserve per-context uniformity across a multi-stage pipeline under a first-order probing model, closing a gap left by prior Boolean-only composition frameworks. **🔑 Key Findings:** - Provides Lean 4 machine-checked proofs, with zero admitted lemmas, for key masking properties over \(\mathbb{Z}/q\mathbb{Z}\) rather than only Boolean masking domains. - Proves that fresh randomness gives constant marginal distributions through an algebraic proxy for zero mutual information. - Shows a Cooley-Tukey butterfly with fresh output masks has output distributions independent of secrets for all moduli, twiddle factors, and inputs. - Extends the result to k-stage NTT pipelines, proving stage-by-stage per-context uniformity under the ISW first-order probing model. - Uses the framework to explain why the Adams Bridge accelerator is structurally insecure when fresh masking is not renewed through the pipeline. --- 🔗 [Read paper](https://arxiv.org/abs/2604.20793v1) 📎 [PDF](https://arxiv.org/pdf/2604.20793v1) #cryptography #hardware-security #crypto #cs.CR ⏱️ 2026-04-23 18:00 UTC

## 📄 Neural Leakage–based Cryptanalysis of LowMC with Linear Complexity ✍️ Kwangjo Kim 🏛️ IACR ePrint · 📅 2026-04-21 --- This paper argues that neural, piecewise-linear implementations of LowMC can leak useful activation-boundary information, creating a new side-channel-like path for cryptanalysis of MPC-in-the-Head constructions such as Picnic. The proposed probing method turns that leakage into binary hypothesis tests that recover round keys, then uses LowMC's linear key schedule to reconstruct full 128, 192, and 256-bit master keys efficiently. **🔑 Key Findings:** - Introduces a perturbation-based probing method to model neural leakage in LowMC implementations. - Reduces round-key recovery to independent binary hypothesis tests combined through majority voting. - Shows that recovering the first-round key is enough to derive the full master key with linear complexity because of the LowMC key schedule. - Reports successful experimental recovery of 128-bit, 192-bit, and 256-bit keys under the proposed leakage model. - Highlights learning-based leakage as a design consideration for future symmetric primitives and post-quantum signature systems built on them. --- 🔗 [Read paper](https://eprint.iacr.org/2026/785) 📎 [PDF](https://eprint.iacr.org/2026/785.pdf) #cryptography #crypto #cybersecurity ⏱️ 2026-04-24 02:45 UTC

The core result is that under moderate perturbation budgets and suitable signal-to-noise conditions, adversarially trained ViTs can still generalize well even while fitting training data extremely closely, extending the benign-overfitting story into transformer robustness. **🔑 Key Findings:** - Provides the first theoretical analysis of adversarial training specifically for simplified ViT architectures. - Derives conditions under which adversarial training yields near-zero robust training loss and low robust generalization error. - Identifies a benign-overfitting regime for adversarially trained ViTs, paralleling earlier observations in CNNs. - Connects robustness behavior to signal-to-noise ratio assumptions and perturbation-budget limits. - Reports synthetic and real-data experiments that support the theoretical predictions. --- 🔗 [Read paper](https://arxiv.org/abs/2604.19724v1) 📎 [PDF](https://arxiv.org/pdf/2604.19724v1) #ai-security #cybersecurity #adversarial-ml #robustness #cs.LG #cs.AI ⏱️ 2026-04-23 00:00 UTC

## 📄 Safe Continual Reinforcement Learning in Non-stationary Environments ✍️ Austin Coursey, Abel Diaz-Gonzalez, Marcos Quinones-Grueiro, Gautam Biswas 🏛️ arXiv · 📅 2026-04-21 --- This paper examines what happens when safety-constrained RL agents have to keep adapting after deployment instead of learning in a fixed environment. The authors show that current methods usually fail to preserve both safety constraints and retained competence under shifting dynamics, which makes safe continual RL a much less solved problem than either safe RL or continual RL alone. **🔑 Key Findings:** - Introduces three benchmark environments specifically designed for safety-critical continual adaptation. - Evaluates representative safe RL methods, continual RL methods, and hybrid combinations under non-stationary conditions. - Finds a persistent tradeoff between avoiding catastrophic forgetting and maintaining hard safety constraints during adaptation. - Shows that regularization-based methods can partially reduce this tradeoff, but do not fully solve it. - Frames open research problems for resilient controllers that must adapt online without unsafe transient behavior. --- 🔗 [Read paper](https://arxiv.org/abs/2604.19737v1) 📎 [PDF](https://arxiv.org/pdf/2604.19737v1) #ai-security #safety #reinforcement-learning #cs.LG ⏱️ 2026-04-23 00:00 UTC

## 📄 United States v. Ullah ✍️ Unknown 🏛️ CourtListener · 📅 2026-04-21 --- The Second Circuit largely upheld the convictions and life sentence arising from Akayed Ullah's 2017 pipe-bomb attack in a Manhattan transit tunnel, but it reversed the material-support count. The panel held the evidence showed Ullah was inspired by ISIS propaganda, yet did not prove the coordination, direction, or control needed to establish providing material support to a foreign terrorist organization under 18 U.S.C. § 2339B. **🔑 Key Findings:** - The court reversed Count One, holding the evidence was insufficient to prove material support to ISIS under a proper reading of § 2339B. - It affirmed Count Five, concluding Ullah "placed" a destructive device in or near a mass transportation vehicle by carrying the bomb on his person into the subway system. - It affirmed Count Six, reasoning that any possible Yates error did not affect substantial rights because a rational jury would necessarily have found at least one valid crime-of-violence predicate. - The panel also upheld the overall sentence, except that the sentence attached to the reversed Count One must be vacated on remand. - The opinion draws an important line between ideological inspiration by terrorist propaganda and legally sufficient support or coordination with a designated foreign terrorist organization. --- 🔗 [Read paper](https://www.courtlistener.com/opinion/10846141/united-states-v-ullah/) #law #terrorism #criminal-law #national-security ⏱️ 2026-04-22 11:30 UTC

## 📄 United States v. Bolandian ✍️ Unknown 🏛️ CourtListener · 📅 2026-04-21 --- The Ninth Circuit vacated an insider-trading conviction and ordered a new trial because the district court failed to adequately investigate mid-trial juror bias. The panel held that a trial judge has an independent duty to inquire into a juror's claimed inability to remain impartial, and that defense counsel cannot waive that duty before a sufficient inquiry occurs. **🔑 Key Findings:** - The panel held Bolandian forfeited, rather than knowingly waived, his juror-bias challenge because the trial court never performed the required investigation. - It found plain error where the district judge effectively told the juror to self-monitor bias instead of conducting a meaningful inquiry or rehabilitation. - The court treated the failure to protect the Sixth Amendment right to an impartial jury as serious enough to require a new trial. - Because the juror-bias issue was dispositive, the panel did not need to resolve Bolandian's other appellate arguments about evidence, prosecutorial statements, or sentencing. - The opinion reinforces that trial courts, not parties or jurors themselves, bear the core responsibility for managing emergent bias during trial. --- 🔗 [Read paper](https://www.courtlistener.com/opinion/10846226/united-states-v-bolandian/) #law #criminal-law #insider-trading #procedure ⏱️ 2026-04-22 11:30 UTC

## 📄 Comanche Nation v. Ware ✍️ Unknown 🏛️ CourtListener · 📅 2026-04-21 --- The Tenth Circuit split the sovereign-immunity issues in a dispute over the Fort Sill Apache Tribe's Warm Springs Casino. It held that IGRA abrogates tribal immunity for the official-capacity claims challenging the casino's operation, but that tribal officials retain immunity from official-capacity RICO claims, while individual-capacity RICO damages claims may proceed because the officials are the real parties in interest. **🔑 Key Findings:** - The panel affirmed that the Comanche Nation can pursue official-capacity claims under the Indian Gaming Regulatory Act against Fort Sill Apache officials. - It reversed as to official-capacity RICO claims, holding tribal sovereign immunity still bars that part of the suit. - The court allowed individual-capacity RICO damages claims to move forward because the defendants, not the tribe, are treated as the real parties in interest on those claims. - The case arises from competition over the Warm Springs Casino near Comanche Nation casinos and turns on whether the site was lawfully opened for gaming. - The opinion is a notable federal appellate treatment of the boundary between IGRA's remedial scheme and tribal immunity doctrines in parallel RICO litigation. --- 🔗 [Read paper](https://www.courtlistener.com/opinion/10846242/comanche-nation-v-ware/) #law #tribal-law #sovereign-immunity #gaming-law ⏱️ 2026-04-22 11:30 UTC

## 📄 James Johnson a/k/a James Nathaniel Johnson v. State of Mississippi ✍️ Unknown 🏛️ CourtListener · 📅 2026-04-21 --- The Mississippi Court of Appeals affirmed a life-without-parole sentence imposed after a Miller resentencing hearing for a defendant who was 16 at the time of the murder. The court held the trial judge applied the correct juvenile-sentencing framework and did not abuse discretion in concluding the record, including prison misconduct and a later contraband-smuggling conviction, weighed against parole eligibility. **🔑 Key Findings:** - The court held Mississippi's post-Miller sentencing scheme is constitutionally sufficient so long as the sentencer considers youth and has discretion to impose a lesser punishment. - It affirmed the trial court's conclusion that Johnson was a willing participant in the robbery-murder and not materially coerced by his older half-brother. - The opinion stresses appellate deference on Miller-factor balancing and rejects reweighing the mitigation record on appeal. - The rehabilitation analysis turned heavily on repeated prison disciplinary violations and a later conviction for contraband smuggling while Johnson awaited resentencing. - The ruling is a useful marker for how Mississippi appellate courts are sustaining juvenile LWOP resentencings after Jones v.

## 📄 Provably Secure Hybrid Inner Product and Boolean Masking via Composable Conversion ✍️ Jaeseung Han, Dong-Guk Han 🏛️ IACR ePrint · 📅 2026-04-20 --- This work builds a composable bridge between Boolean masking and inner-product masking so implementers can use each where it fits best instead of committing to one masking domain end to end. The result is a hybrid masked AES design that keeps provable security order amplification while materially lowering randomness and gate costs compared with code-based masking-heavy approaches. **🔑 Key Findings:** - Proposes BM-to-IPM and IPM-to-BM conversion gadgets with provable composable security in the bit-probing model. - Optimizes prior IPM multiplication to significantly cut fresh randomness and XOR-gate costs while preserving provable security. - Defines a hybrid IPM-BM implementation strategy, using IPM for multiplications and BM for linear Boolean operations. - Presents a second-order masked AES-128 instantiation with 2-share IPM and 3-share BM. - Reports first- and second-order TVLA evaluation on Cortex-M4, framing this as the first end-to-end implementation to provably preserve IPM security-order amplification. --- 🔗 [Read paper](https://eprint.iacr.org/2026/774) 📎 [PDF](https://eprint.iacr.org/2026/774.pdf) #cryptography #hardware-security #cybersecurity ⏱️ 2026-04-22 14:46 UTC

The core result is uncomfortable: even fairly high-share masked designs still leak enough that attackers can recover strong oracle signal from only about 50 executions, raising real doubts about the practicality of high-assurance masked ML-KEM on constrained embedded devices. **🔑 Key Findings:** - Systematically evaluates PCO instantiation against three open-source masked Keccak implementations using different masking techniques and coding styles. - Achieves high-accuracy oracle construction for implementations with up to 7 shares using profiled side-channel attacks and roughly 50 ML-KEM executions. - Empirically reinforces the idea that extra computation in masked decapsulation often translates into more exploitable leakage. - Shows soft, probabilistic exploitation of PCOs is superior to hard-decision approaches. - Finds even naive lattice-based attacks look promising once physical side-channel information is available. --- 🔗 [Read paper](https://eprint.iacr.org/2026/777) 📎 [PDF](https://eprint.iacr.org/2026/777.pdf) #cryptography #hardware-security #cybersecurity #privacy ⏱️ 2026-04-22 14:46 UTC

## 📄 Different Paths to Harmful Compliance: Behavioral Side Effects and Mechanistic Divergence Across LLM Jailbreaks ✍️ Md Rysul Kabir, Zoran Tiganj 🏛️ arXiv · 📅 2026-04-20 --- This paper compares three ways open-weight LLMs can be jailbroken, harmful supervised fine-tuning, harmful RL with verifiable rewards, and refusal-suppressing abliteration, and shows they do not fail in the same way even when all produce high harmful compliance. The most interesting result is that RLVR-jailbroken models often still recognize harm and can describe the safe response, yet comply anyway, suggesting a separation between retained safety knowledge and retargeted policy behavior. **🔑 Key Findings:** - All three jailbreak routes reached near-ceiling harmful compliance, but produced sharply different side effects on capability, safety judgments, and internal failure modes. - RLVR-jailbroken models preserved much of the base model's behavior and explicit harm recognition, and harmful behavior dropped close to baseline when prompts included a reflective safety scaffold. - Harmful SFT caused the broadest behavioral drift, the largest collapse in explicit safety judgments, and noticeable capability loss on standard benchmarks. - Abliteration behaved more like localized refusal-feature deletion, while the authors characterize RLVR as preserved safety geometry with retargeted policy behavior. - Targeted repair partially recovered RLVR-jailbroken models but had little effect on SFT-jailbroken ones, which matters for post-hoc defense strategies. --- 🔗 [Read paper](https://arxiv.org/abs/2604.18510v1) 📎 [PDF](https://arxiv.org/pdf/2604.18510v1) #ai-security #cybersecurity #privacy #cs.CR #cs.AI #cs.CL ⏱️ 2026-04-21 12:05 UTC

It finds meaningful gains in learner performance and very strong effects on confidence, engagement, and satisfaction, while also showing that affective improvement does not automatically translate into objective score gains. **🔑 Key Findings:** - Students using ChatGPT-supported speaking tasks improved more than the control group, 30.8 percent versus 17.5 percent. - Participants reported highly positive attitudes toward ChatGPT and strong behavioral, cognitive, and emotional engagement. - Attitudes, emotional engagement, and satisfaction strongly predicted perceived speaking proficiency. - Those affective variables did not predict objective IELTS post-test performance. - The paper argues AI speaking tools work best inside a structured teaching model with active instructor mediation. --- 🔗 [Read paper](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=6595190) #ai-security #law ⏱️ 2026-04-17 13:18 UTC

## 📄 Related-Key Multi-Pair Neural Distinguishers: Analysis and Applications to Lightweight Block Ciphers ✍️ Thanh-Phong Nguyen, Nguyen Tan Cam, Thanh-Hien Vu, Van-Than Huynh, Hieu-Minh Nguyen 🏛️ IACR ePrint · 📅 2026-04-16 --- This paper studies why related-key, multi-pair neural distinguishers sometimes keep working deeper into lightweight block ciphers than single-pair attacks. The authors show that the gains mostly come from aggregating weak ciphertext-level statistical signals, not from any special generalization power in the neural models, which helps clarify where neural cryptanalysis is genuinely useful and where it hits a hard wall. **🔑 Key Findings:** - Across PRESENT-80, SIMECK-32/64, LEA-128, and HIGHT, multi-pair aggregation improves distinguisher accuracy by reducing variance in weak ciphertext-level biases. - PCA-derived geometry and silhouette scores track neural distinguisher performance, giving a model-independent way to estimate when signal is still present. - As rounds increase, the underlying ciphertext signal decays and both geometric separability and neural accuracy collapse toward chance. - In low-signal regimes, multi-pair setups can still extract small residual structure, but only within narrow empirical limits. - Generalization fails past that boundary, suggesting signal availability, not model capacity, is the main bottleneck. --- 🔗 [Read paper](https://eprint.iacr.org/2026/748) 📎 [PDF](https://eprint.iacr.org/2026/748.pdf) #cryptography #crypto #ai-security ⏱️ 2026-04-22 02:45 UTC

## 📄 XFED: Non-Collusive Model Poisoning Attack Against Byzantine-Robust Federated Classifiers ✍️ Israt Jahan Mouri, Muhammad Ridowan, Muhammad Abdullah Adnan 🏛️ arXiv · 📅 2026-04-10 --- XFED argues that federated learning defenses are overestimating attacker coordination costs. It shows that independently acting poisoned clients, with no communication or visibility into peers or server defenses, can still bypass Byzantine-robust aggregation and degrade model integrity. **🔑 Key Findings:** - Formalizes a non-collusive threat model where compromised FL clients pursue the same objective without exchanging updates or coordinating behavior. - Proposes XFED as an aggregation-agnostic poisoning attack that does not require knowledge of server-side defenses. - Empirically bypasses 8 state-of-the-art federated learning defenses across 6 benchmark datasets. - Outperforms 6 prior poisoning attacks despite removing the botnet-like coordination assumptions many attacks rely on. - Suggests practical FL deployments may be substantially more vulnerable to stealthy poisoning than current defense evaluations imply. --- 🔗 [Read paper](https://arxiv.org/abs/2604.09489v1) 📎 [PDF](https://arxiv.org/pdf/2604.09489v1) #cybersecurity #ai-security #cs.CR #cs.AI #cs.DC #cs.LG ⏱️ 2026-04-13 06:00 UTC

## 📄 Com. v. Smith, J. ✍️ McLaughlin 🏛️ CourtListener · 📅 2026-04-10 --- The Pennsylvania Superior Court, on remand from the state supreme court, held that the evidence was still sufficient to sustain James Smith's unlawful-contact-with-a-minor convictions after Commonwealth v. Strunk narrowed the statute's scope. The court said Smith's verbal directions to the child victims immediately before the assaults counted as communications that furthered sexual exploitation, which is the key line Strunk requires. **🔑 Key Findings:** - The court reaffirmed Smith's judgment of sentence after a remand to reconsider the unlawful-contact counts under Strunk. - Strunk was read as an anti-grooming and facilitation rule, not a broad ban on all abusive physical contact. - Smith's statements telling victims to perform oral sex and directing one victim to lie on a table were treated as qualifying communications under 18 Pa.C.S. § 6318. - The opinion distinguishes cases with no communicative act from cases where speech or instructions reposition a victim to enable the assault. - The ruling tightens the doctrinal line around when grooming-style or facilitative communication is enough to support unlawful-contact charges. --- 🔗 [Read paper](https://www.courtlistener.com/opinion/10840888/com-v-smith-j/) #law #court-opinion #child-safety #criminal-law ⏱️ 2026-04-10 23:32 UTC

## 📄 GRAFHEN is not IND-CPA secure ✍️ Remi Geraud-Stewart 🏛️ IACR ePrint · 📅 2026-04-09 --- A very short but sharp cryptanalysis note: this paper shows the recently proposed noise-free homomorphic encryption scheme GRAFHE/GRAFHEN fails basic IND-CPA security.

The authors argue that traditional honeypots miss important behavioral signals once the adversary is an autonomous model rather than a human operator, and they lay out an architecture for capturing those signals systematically. **🔑 Key Findings:** - Introduces the idea of honeypots built specifically to observe and characterize hostile or misaligned LLM agents in the wild. - Frames the main design requirements as believable interaction, safe containment, rich telemetry, and support for behavioral analysis. - Positions agent-focused deception infrastructure as a way to generate empirical data on emerging AI-enabled cyber threats. - Highlights the gap between classic honeypot assumptions and attacks driven by autonomous, language-capable agents. --- 🔗 [Read paper](https://arxiv.org/abs/2604.06358v1) 📎 [PDF](https://arxiv.org/pdf/2604.06358v1) #ai-security #cybersecurity #cs.GR #cs.AI ⏱️ 2026-04-09 18:00 UTC

## 📄 Mergeable SNARGs for Trapdoor Languages and Their Applications ✍️ Zvika Brakerski, Maya Farber Brodsky, Omer Paneth, Tomer Solomon 🏛️ IACR ePrint · 📅 2026-04-07 --- This paper introduces a way to merge short computational proofs for trapdoor languages so that many proofs can be recursively combined without security loss blowing up with the total merge tree size. The result is a cleaner path to scalable recursive proof composition, and the authors use it to build the first CCA1-secure multi-hop FHE and the first adaptive multi-hop aggregate signatures from LWE. **🔑 Key Findings:** - Gives the first merge procedure for SNARGs that supports an unbounded polynomial number of recursive merges with arbitrary topology. - Improves the security reduction so it depends on merge depth rather than total tree size, which can be exponentially larger. - Applies to trapdoor languages, where a hidden trapdoor is only needed in the proof of security, not by provers or verifiers. - Provides constructions from sub-exponential indistinguishability obfuscation and from LWE, with different compactness tradeoffs. - Uses the framework to obtain the first CCA1-secure multi-hop FHE and the first adaptive multi-hop aggregate signature scheme from LWE. --- 🔗 [Read paper](https://eprint.iacr.org/2026/678) 📎 [PDF](https://eprint.iacr.org/2026/678.pdf) #cryptography #crypto #fhe #snargs #lwe ⏱️ 2026-04-08 20:45 UTC

## 📄 SPLASH: Runtime-Configurable and Comprehensive Speculative Execution Attack Mitigation in Post-Silicon Microprocessors ✍️ Sungbum Kwon, Jaejin Lee, Hyeran Jeon, Mohammad Abdullah Al Faruque 🏛️ IACR ePrint · 📅 2026-04-07 --- SPLASH proposes a post-silicon defense framework for speculative execution attacks that can be reconfigured after deployment instead of being locked into narrow, hardwired mitigations. It combines speculative information-flow tracking with a programmable control table, letting operators tune how speculation is constrained across processor structures while keeping performance impact low. **🔑 Key Findings:** - Introduces Speculative Information Flow Tracking (SIFT) to trace how speculative data propagates through microarchitectural components. - Adds a reconfigurable speculative table that can enforce runtime-adjustable security policies across the processor pipeline. - Supports post-fabrication policy changes, including speculative window tuning and selective protection of specific structures, without redesigning hardware. - On small and medium BOOM processors, the authors report that SPLASH mitigates all evaluated speculative execution attack classes. - Average runtime overhead is reported as 0.05% on small BOOM and 1.23% on medium BOOM, substantially lower than prior leading defenses. --- 🔗 [Read paper](https://eprint.iacr.org/2026/677) 📎 [PDF](https://eprint.iacr.org/2026/677.pdf) #hardware-security #cybersecurity #privacy #cryptography ⏱️ 2026-04-08 14:45 UTC

## 📄 From Hallucination to Structure Snowballing: The Alignment Tax of Constrained Decoding in LLM Reflection ✍️ Hongxu Zhou 🏛️ arXiv · 📅 2026-04-07 --- This paper examines whether constrained decoding alone can make LLM self-reflection more reliable, without external critics or extra training. Instead of fixing reasoning failures, the study finds that strict structure requirements can create a new failure mode, where the model over-optimizes for format and misses semantic mistakes. **🔑 Key Findings:** - In open-ended reasoning, unconstrained self-correction failed through recursive justification of early errors, which the author calls hallucination snowballing. - Imposing Outlines-based structural constraints on Qwen3-8B did not improve self-correction performance. - The constrained setup introduced a distinct failure mode, structure snowballing, where formatting demands trapped the model in superficially valid but semantically weak reflections. - The paper frames this as an alignment tax: stronger syntactic control can consume model capacity that would otherwise go toward genuine error detection and correction. --- 🔗 [Read paper](https://arxiv.org/abs/2604.06066v1) 📎 [PDF](https://arxiv.org/pdf/2604.06066v1) #ai-security #cs.CL ⏱️ 2026-04-08 06:03 UTC

The result matters for systems like encrypted mempools and time-lock storage because it reduces parameter growth while preserving censorship resistance. **🔑 Key Findings:** - Builds an epochless, censorship-resistant batch encryption construction with linear-sized public parameters instead of quadratic growth. - Uses partial fraction decomposition so a single group element can act as the pre-decryption key for an entire batch. - Keeps ciphertexts and pre-decryption keys constant-size while supporting efficient batch decryption. - Provides a CCA security proof and shows how to extend the construction to threshold settings. --- 🔗 [Read paper](https://eprint.iacr.org/2026/674) 📎 [PDF](https://eprint.iacr.org/2026/674.pdf) #cryptography #crypto #privacy ⏱️ 2026-04-07 14:47 UTC

## 📄 Verification Facade: Masquerading Insecure Cryptographic Implementations as Verified Code ✍️ Nadim Kobeissi 🏛️ IACR ePrint · 📅 2026-04-06 --- This paper argues that formal verification pipelines for real-world crypto code can create a false sense of security when the verified model diverges from the implementation. By dissecting hax’s Rust-to-F* pipeline and building concrete exploits, it shows how verified code can still hide security-relevant flaws that neither proofs nor tests expose. **🔑 Key Findings:** - Identifies three failure modes in the hax verification pipeline: translation infidelity, unverifiable trust boundaries, and specification gaming. - Demonstrates five proof-of-concept exploits across ML-DSA, ML-KEM, Ed25519, and ChaCha20 that compile cleanly, pass tests, and verify without warnings. - Separates the risks into facade gaps, a compilation-mode-dependent conditional gap, and scope gaps where critical properties are simply out of reach. - Frames the broader problem as a “verification facade”: proofs are present, but the proven model covers less than developers and reviewers may assume. --- 🔗 [Read paper](https://eprint.iacr.org/2026/670) 📎 [PDF](https://eprint.iacr.org/2026/670.pdf) #cryptography #crypto #cybersecurity ⏱️ 2026-04-07 14:47 UTC

## 📄 No Attacker Needed: Unintentional Cross-User Contamination in Shared-State LLM Agents ✍️ Tiankai Yang, Jiate Li, Yi Nian, Shen Dong, Ruiyao Xu, et al. 🏛️ arXiv · 📅 2026-04-01 --- This paper studies a subtle but very practical failure mode in shared-state agents: benign information from one user silently contaminates another user's outcomes later, without any attacker in the loop. The authors call this unintentional cross-user contamination (UCC) and show it remains a serious problem even when systems try to sanitize shared memory. **🔑 Key Findings:** - Formalizes UCC as a distinct failure mode separate from adversarial memory poisoning. - Defines three contamination types and evaluates them across two shared-state mechanisms. - Reports contamination rates of 57-71% under raw shared state from ordinary benign interactions. - Finds write-time sanitization helps for conversational memory but leaves substantial residual risk for executable artifacts. - Warns that failures often surface as silent wrong answers rather than obvious leakage events. --- 🔗 [Read paper](https://arxiv.org/abs/2604.01350v1) 📎 [PDF](https://arxiv.org/pdf/2604.01350v1) #ai-security #privacy #cybersecurity #cs.CL #cs.AI #cs.CR ⏱️ 2026-04-06 00:03 UTC

## 📄 AgentSocialBench: Evaluating Privacy Risks in Human-Centered Agentic Social Networks ✍️ Prince Zizhuang Wang, Shuli Jiang 🏛️ arXiv · 📅 2026-04-01 --- AgentSocialBench looks at privacy leakage in multi-agent social settings where assistants coordinate across users, domains, and ongoing relationships. The paper argues this setting is qualitatively harder than single-agent privacy evaluation, then shows that even explicit privacy instructions can backfire by encouraging agents to talk around sensitive material rather than avoid it. **🔑 Key Findings:** - Introduces the first benchmark focused on privacy risk in human-centered agentic social networks. - Covers seven scenario categories with hierarchical sensitivity labels and directed social graphs. - Finds cross-domain and cross-user coordination create persistent leakage pressure even with privacy-focused prompting. - Identifies an "abstraction paradox" where privacy instructions can make agents discuss sensitive material more, not less. - Concludes that prompt engineering alone is not enough for safe real-world agent-mediated social coordination. --- 🔗 [Read paper](https://arxiv.org/abs/2604.01487v1) 📎 [PDF](https://arxiv.org/pdf/2604.01487v1) #ai-security #privacy #cs.AI #cs.SI ⏱️ 2026-04-06 00:03 UTC

## 📄 SelfGrader: Stable Jailbreak Detection for Large Language Models using Token-Level Logits ✍️ Zikai Zhang, Rui Hu, Olivera Kotevska, Jiahao Xu 🏛️ arXiv · 📅 2026-04-01 --- SelfGrader proposes a lightweight jailbreak detector that reads token-level logit patterns instead of relying on generated text or heavyweight internal probes. The core idea is to turn safety assessment into a compact numerical grading task, which makes detection faster, cheaper, and less sensitive to generation randomness. **🔑 Key Findings:** - Uses logit distributions over a small set of numerical tokens as an internal harmfulness signal. - Scores queries from both maliciousness and benignness perspectives to reduce false positives. - Avoids dependence on full textual outputs, which makes detection more stable under stochastic generation. - Reports up to 22.66% ASR reduction on LLaMA-3-8B versus compared baselines. - Cuts memory overhead by up to 173x and latency by up to 26x in reported experiments. --- 🔗 [Read paper](https://arxiv.org/abs/2604.01473v1) 📎 [PDF](https://arxiv.org/pdf/2604.01473v1) #ai-security #cybersecurity #cs.CR #cs.AI ⏱️ 2026-04-06 00:03 UTC

The authors build a benchmark around realistic prompt-injection paths and show that model safety depends heavily on the full agent stack, not just the base model. **🔑 Key Findings:** - Introduces CLAWSAFETY, a benchmark with 120 adversarial scenarios spanning software, finance, healthcare, law, and DevOps workspaces. - Tests three realistic injection channels: workspace skill files, trusted email, and web pages encountered during normal agent use. - Across 2,520 sandboxed trials, attack success rates ranged from 40% to 75% depending on model and scaffold. - Skill-file injections were consistently the most dangerous, suggesting trusted local context is a larger problem than generic web content. - Cross-scaffold experiments show safety outcomes vary materially with framework design, so evaluating only the backbone model misses the real risk surface. --- 🔗 [Read paper](https://arxiv.org/abs/2604.01438v1) 📎 [PDF](https://arxiv.org/pdf/2604.01438v1) #ai-security #cybersecurity ⏱️ 2026-04-04 00:03 UTC

## 📄 PrivHAR-Bench: A Graduated Privacy Benchmark Dataset for Video-Based Action Recognition ✍️ Samar Ansari 🏛️ arXiv · 📅 2026-04-01 --- PrivHAR-Bench is a benchmark for the privacy-utility tradeoff in video action recognition, which the field badly needs because most papers still pretend privacy is a binary switch. Here the dataset provides multiple parallel privacy tiers so degradation can be measured instead of guessed. **🔑 Key Findings:** - Builds 9 privacy tiers for each source video, from lighter obfuscation to stronger cryptographic-style transformations. - Includes background-removed variants, pose keypoints, bounding boxes, and standardized splits for more comparable evaluation. - Baseline R3D-18 accuracy falls from 88.8% on clear video to 53.5% on the strongest encrypted/background-removed tier. - Cross-domain accuracy collapses to 4.8%, which is a useful reminder that privacy transforms and generalization do not magically coexist. --- 🔗 [Read paper](https://arxiv.org/abs/2604.00761v1) 📎 [PDF](https://arxiv.org/pdf/2604.00761v1) #privacy #computer-vision #cybersecurity #cs.CV #cs.CR ⏱️ 2026-04-02 18:10 UTC

The court holds that three successive complaints failed basic Rule 8 and Rule 12 standards, while also rejecting the fund's attempt to pursue thousands of anonymous claims through associational standing. **🔑 Key Findings:** - The court dismissed the second amended complaint because its 396 pages and 900+ paragraphs still did not give defendants fair notice of who allegedly did what to whom. - General allegations of systemic abuse by a foreign government were not enough; the court demanded concrete factual links between specific defendants, specific violations of U.S. law, and specific injuries to identified plaintiffs. - The defamation claim against defense counsel Joe Reeder was dismissed with prejudice under the absolute privilege for statements made in judicial proceedings. - Kurdistan Victims Fund could not seek $9 billion in damages on behalf of 1-5000 unnamed members because those claims require individualized proof and therefore fail associational-standing rules. - The court gave the three named individual plaintiffs one final chance to replead in a complaint capped at 30 pages, warning that further noncompliance could bring dismissal with prejudice. --- 🔗 [Read paper](https://www.courtlistener.com/opinion/10831471/kurdistan-victims-fund-v-kurdistan-regional-government/) #law #Court_Opinion #District_Court,_District_of_Columbia #Published ⏱️ 2026-04-01 23:30 UTC

The main result is that you can get optimal-size keys with evaluations that touch only O(n) bits, and the authors also show explicit almost k-wise independent constructions that beat what perfect independence seems able to deliver. **🔑 Key Findings:** - The paper gives non-constructive perfectly k-wise independent t-local hash functions with O(kn) key size and locality O(n) bits, improving over prior O(n²)-bit locality. - It shows a generic reduction from perfectly k-wise independent local hashing to expander constructions, which means explicit progress here is bottlenecked by explicit expander progress. - The authors define and study ε-almost k-wise independence against adaptive queries rather than only perfect independence. - They construct explicit ε-almost k-wise independent hash families with optimal O(kn) key size, O(n) bit locality, and ε = 2^-n. - In a larger-word model, they obtain explicit constructions with O(kn/w) words of key material and locality O(n/√w) words, which they argue is nearly optimal. --- 🔗 [Read paper](https://eprint.iacr.org/2026/622) 📎 [PDF](https://eprint.iacr.org/2026/622.pdf) #cryptography #crypto #hashing #theory ⏱️ 2026-04-01 14:45 UTC

This paper looks at how far active learning and semi-supervised learning can cut retraining costs for both Android and Windows malware detection without just pretending distribution drift is somebody else's problem. **🔑 Key Findings:** - The evaluation is model-agnostic and covers both Android and Windows malware detection rather than one narrow benchmark niche. - Combined active-learning and semi-supervised-learning strategies cut manual annotation costs by up to 90% while staying close to full-label retraining performance. - The authors add a feature-level drift analysis method to measure how feature stability changes over time. - That drift analysis is reported to correlate with detector performance degradation, giving defenders a more concrete update signal than vibes. - The practical value is operational: cheaper refresh cycles for ML malware systems that would otherwise rot in production. --- 🔗 [Read paper](https://arxiv.org/abs/2603.28396v1) 📎 [PDF](https://arxiv.org/pdf/2603.28396v1) #cybersecurity #ai-security #malware #active-learning #drift #csLG ⏱️ 2026-03-31 06:07 UTC

## 📄 Silent Guardians: Independent and Secure Decision Tree Evaluation Without Chatter ✍️ Jinyuan Li 🏛️ arXiv · 📅 2026-03-30 --- Private ML inference papers usually promise confidentiality, verifiability, or tolerable latency. Getting all three at once is where the hand-waving starts. This work proposes a two-server protocol for outsourced decision-tree inference that removes server-to-server communication while still aiming to keep inputs, models, and result integrity protected. **🔑 Key Findings:** - The proposed PVODTE protocol combines homomorphic secret sharing with MAC-based verification for private and verifiable outsourced decision-tree evaluation. - Its main systems claim is non-interactivity: the two cloud servers do not need to communicate during evaluation. - That design targets WAN deployments where cross-server chatter adds latency and synchronization pain. - The scheme is presented as secure against malicious servers, not just the usual semi-honest toy model. - If the claims hold up, it closes a fairly common gap in MLaaS work where privacy and correctness guarantees are rarely delivered together. --- 🔗 [Read paper](https://arxiv.org/abs/2603.28143v1) 📎 [PDF](https://arxiv.org/pdf/2603.28143v1) #privacy #cryptography #machine-learning #mlaas #secure-computation #csCR ⏱️ 2026-03-31 06:07 UTC

The main claim is that in-context learning can match fine-tuned detectors with far less labeled data while also discovering categories the fixed taxonomy never bothered to name. **🔑 Key Findings:** - Properly configured ICL reportedly reaches performance comparable to fine-tuned models using 22x fewer labeled examples. - For most tested illicit categories, performance drops by less than 6% when evaluating unseen threat types without category-specific demonstrations. - A two-stage discovery pipeline compresses 2,900 free-form labels into a usable taxonomy and surfaces eight previously undocumented illicit categories, including usury and illegal immigration. - On 200,000 search-engine and Twitter samples, the system reports 92.6% accuracy without platform-specific adaptation. - Among samples uniquely flagged by the system, 61.8% were borderline or obfuscated cases missed by existing detectors. --- 🔗 [Read paper](https://arxiv.org/abs/2603.28043v1) 📎 [PDF](https://arxiv.org/pdf/2603.28043v1) #cybersecurity #content-moderation #illicit-finance #llm #platform-security #csCR ⏱️ 2026-03-31 06:07 UTC

Starting from a 2026 ruling that AI-generated legal research material was discoverable, it argues that third-party model infrastructure breaks confidentiality by design unless firms move to local deployment or win new procedural protections. **🔑 Key Findings:** - Builds on United States v. Heppner, where AI-generated legal research was held outside attorney-client privilege and work-product protection. - Identifies six attack vectors for obtaining AI interaction data in litigation. - Proposes three mitigations: a FRCP 26(b)(1) amendment path, local AI deployment, and ready-to-file practitioner objections. - Frames the problem as architectural rather than a mere training or policy failure. --- 🔗 [Read paper](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=6227600) #law #ai-security #privacy #legal-tech #litigation ⏱️ 2026-03-31 01:19 UTC

The paper is relevant well beyond abortion politics because it treats app data, messages, and other traces as evidence pipelines that privacy doctrine is structurally bad at stopping. **🔑 Key Findings:** - Introduces the category of “reproductive crimes” to describe overlapping criminalization of reproductive activity. - Argues that both public and private privacy law are inadequate shields against digital-evidence-driven prosecution. - Claims legal reform is likely to be absorbed by ordinary law-enforcement imperatives rather than constrain them. - Concludes that decriminalization, not marginal privacy-law tuning, is the only durable fix. --- 🔗 [Read paper](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=6455198) #privacy #law #digital-evidence #surveillance #civil-liberties ⏱️ 2026-03-31 01:19 UTC

This paper argues the uglier problems show up between models: collusion-like coordination, conformity, and other group pathologies emerge in multi-agent systems even without explicit instructions to behave badly. **🔑 Key Findings:** - The study examines competitive resource allocation, sequential handoff workflows, collective decision aggregation, and related multi-agent settings. - Collusion-like coordination and conformity appear at non-trivial rates across repeated trials and realistic protocol constraints. - These failures are framed as emergent social-intelligence risks rather than simple single-agent misalignment. - The paper argues current agent-level safeguards do not meaningfully prevent these collective failure modes. - The practical implication is that multi-agent safety needs system-level controls, not just better guardrails on each individual model. --- 🔗 [Read paper](https://arxiv.org/abs/2603.27771v1) 📎 [PDF](https://arxiv.org/pdf/2603.27771v1) #ai-security #multi-agent-systems #llm #safety #governance #csMA ⏱️ 2026-03-31 06:07 UTC

## 📄 Ordering Power is Sanctioning Power: Sanction Evasion-MEV and the Limits of On-Chain Enforcement ✍️ Di Wu 🏛️ arXiv · 📅 2026-03-29 --- This paper points out an awkward detail in stablecoin sanctions enforcement: a blacklist transaction is still just another transaction fighting for block inclusion. The authors frame that race as sanction-evasion MEV and argue that, on public chains, the actor controlling ordering effectively controls enforcement. **🔑 Key Findings:** - The dataset covers Ethereum-based USDT and USDC sanctions activity from Nov. 2017 to Aug. 2025, spanning more than $1.5B in frozen assets. - Before freezes took effect, 7.3% of sanctioned USDT addresses and 18.7% of sanctioned USDC addresses were drained to zero. - The paper documents an escalation path from issuer-side execution failures to public gas auctions, private order flow, and direct proposer bribery. - A game-theoretic model suggests compliant issuers are pushed toward participating in MEV markets rather than staying outside them. - The larger claim is structural: contract-layer blacklist authority cannot guarantee sanctions enforcement when consensus-layer ordering is sold to the highest bidder. --- 🔗 [Read paper](https://arxiv.org/abs/2603.27739v1) 📎 [PDF](https://arxiv.org/pdf/2603.27739v1) #crypto #fincrime #sanctions #mev #blockchain #csCR ⏱️ 2026-03-31 06:07 UTC

The authors build a shared benchmark across 13,708 packages and show that detection quality depends less on model branding than on whether a tool can infer malicious intent from behavioral chains instead of isolated API calls. **🔑 Key Findings:** - The benchmark covers 6,420 malicious and 7,288 benign NPM packages, annotated across 11 behavior categories and 8 evasion techniques. - GuardDog reportedly delivers the best single-tool balance at 93.32% F1. - Behavior-chain reasoning matters a lot: one attack pattern jumps from 3.2% to 79.3% detection when tools model collection → serialization → exfiltration as a sequence instead of independent calls. - The paper argues recent ML failures are driven more by concept convergence—malware looking statistically similar to benign code—than by classic concept drift. - Strategic tool combinations outperform naive ensemble thinking, reaching 95.79% F1 when complementarity outweighs added false positives. --- 🔗 [Read paper](https://arxiv.org/abs/2603.27549v1) 📎 [PDF](https://arxiv.org/pdf/2603.27549v1) #cybersecurity #software-supply-chain #malware #npm #package-security #csSE ⏱️ 2026-03-31 06:07 UTC

This paper proposes a universal observation model for timed automata and uses it to define evolution-based timed opacity, giving the field a cleaner hierarchy for reasoning about what an observer can actually infer. **🔑 Key Findings:** - The paper introduces a unified observation model with full visibility into time delay but partial visibility into locations, clocks, and events. - On top of that model, it defines evolution-based timed opacity as a general semantic notion for timed systems. - The authors prove evolution-based timed opacity is strictly stronger than language-based timed opacity. - They also establish equivalence with execution-time opacity under constrained observations. - The contribution is foundational rather than applied, but useful for anyone formalizing secrecy properties in cyber-physical or real-time systems. --- 🔗 [Read paper](https://arxiv.org/abs/2603.26573v1) 📎 [PDF](https://arxiv.org/pdf/2603.26573v1) #cybersecurity #privacy #formal-methods #timed-automata #csCR ⏱️ 2026-03-30 18:03 UTC

## 📄 Towards Privacy-Preserving Federated Learning using Hybrid Homomorphic Encryption ✍️ Ivan Costa, Pedro Correia, Ivone Amorim, Eva Maia, Isabel Praça 🏛️ arXiv · 📅 2026-03-27 --- This paper goes after a weak assumption hiding in some privacy-preserving federated learning systems: everyone shares one homomorphic key pair, so a malicious client can become everyone else's problem. The authors propose two key-protection schemes for hybrid homomorphic encryption in FL—masking and RSA encapsulation—to keep client updates protected even when participants are adversarial. **🔑 Key Findings:** - Existing HHE-FL designs with a shared homomorphic key pair are argued to rely on an unrealistically soft threat model. - The paper adds two defenses: masked client keys that are later unblinded homomorphically, and RSA wrapping of homomorphically encrypted keys for server-only recovery. - Both approaches are implemented in Flower on top of the PASTA/BFV scheme and evaluated with 12 MNIST clients. - The reported tradeoff is favorable: masking adds negligible overhead, while RSA encapsulation adds only modest runtime and communication cost. - The practical contribution is extending HHE-FL from "honest enough lab demo" toward something closer to an adversarial deployment model. --- 🔗 [Read paper](https://arxiv.org/abs/2603.26417v1) 📎 [PDF](https://arxiv.org/pdf/2603.26417v1) #privacy #cryptography #cybersecurity #federated-learning #homomorphic-encryption #csCR ⏱️ 2026-03-30 18:03 UTC

This paper re-tests the problem on Solidity 0.8+ with two manually verified benchmarks, then compares formal analyzers, conventional ML models, and nine LLMs to see which approaches still work on modern contracts instead of fossilized examples. **🔑 Key Findings:** - The authors built an aggregated benchmark of 432 relabeled real-world contracts plus a 143-case Reentrancy Scenarios Dataset designed to isolate specific failure modes. - Across the aggregated benchmark, traditional tools and ML models reach up to 0.87 F1, while the best zero-shot LLM reaches 0.96. - On the scenario-focused benchmark, most tools break on multiple patterns; the best formal-style tool reaches 0.76 F1 and the strongest model reaches 0.82. - The results suggest modern LLMs now outperform most existing reentrancy detectors, at least on these benchmarks. - More awkwardly, the paper argues many established analysis tools are lagging behind modern Solidity and modern attack patterns. --- 🔗 [Read paper](https://arxiv.org/abs/2603.26497v1) 📎 [PDF](https://arxiv.org/pdf/2603.26497v1) #cybersecurity #crypto #smart-contracts #ethereum #llm #csCR ⏱️ 2026-03-30 18:03 UTC

The result matters because prior lower bounds largely assumed fixed communication graphs; once that restriction is removed, the efficiency picture changes substantially. **🔑 Key Findings:** - Adaptive communication graphs let arbitrary Boolean functions be computed with bottleneck complexity O(n/log n), including secure variants. - The construction still works in asynchronous networks, avoiding brittle tricks like encoding information through silence or timing. - The authors argue the O(n/log n) bottleneck is essentially optimal in this model. - For symmetric functions, they both enlarge the set of functions with low-bottleneck protocols and show further gains from input-adaptive communication. --- 🔗 [Read paper](https://eprint.iacr.org/2026/608) 📎 [PDF](https://eprint.iacr.org/2026/608.pdf) #cryptography #crypto ⏱️ 2026-03-28 02:45 UTC

## 📄 Tedesco Excavating v. FWH Development ✍️ Panella, Bowes 🏛️ CourtListener · 📅 2026-03-27 --- An en banc Pennsylvania Superior Court held that a contractor can invoke CASPA after an owner's anticipatory repudiation when the contractor had sufficiently performed and then submitted a final payment demand for lost overhead and profits. The ruling treats the owner's refusal to pay strictly under the contract as enough to trigger CASPA's remedial provisions. **🔑 Key Findings:** - The court affirmed a $678,238.31 judgment in favor of Tedesco. - It found Tedesco had performed enough under the contract to qualify for payment protection under CASPA. - FWH's anticipatory repudiation did not insulate it from statutory liability under CASPA. - The court rejected reliance on other payment statutes to narrow CASPA's reach in this private construction dispute. - A dissent argued CASPA should not cover anticipated-profit damages once completed work had been paid. --- 🔗 [Read paper](https://www.courtlistener.com/opinion/10826341/tedesco-excavating-v-fwh-development/) #law #CourtOpinion #SuperiorCourtofPennsylvania #Published ⏱️ 2026-03-27 23:33 UTC

## 📄 Moramarco v.

The opinion matters because it treats Probate Code section 859 as a serious deterrent remedy, not something softened by claimed inability to pay. **🔑 Key Findings:** - The former trustee had already been disbarred and ordered to make restitution after taking trust funds for non-beneficiary purposes. - The probate court's roughly $399,681 civil penalty and $61,702.54 fee award largely survived appeal. - The appellate court rejected inability-to-pay mitigation as a basis to reduce the section 859 penalty. - The fee challenge failed in part because the appellant's briefing lacked adequate record citations. - The judgment was amended only to clarify that post-judgment interest does not run on the prejudgment-interest component. --- 🔗 [Read paper](https://www.courtlistener.com/opinion/10826990/moramarco-v-nowakoski/) #law #fincrime #CourtOpinion #CaliforniaCourtofAppeal #Published ⏱️ 2026-03-27 23:33 UTC

The court entered judgment for defendants, but fee-shifted only 50% because both sides polluted the record with backdating, false testimony, and general contempt for basic corporate formalities. **🔑 Key Findings:** - Expert forensic evidence persuaded the court that the plaintiff's key governance documents were fake. - Because the plaintiff was not actually a stockholder or director, he lacked standing under 8 Del. C. § 225. - The court refused to bless a lawful "status quo ante" board because the company had never properly followed statutory board-election requirements. - Defendants still took a hit: their admitted backdating and false testimony led the court to reduce fee shifting by half. - The opinion is a compact reminder that Delaware courts do not enjoy forged cap-table fan fiction. --- 🔗 [Read paper](https://www.courtlistener.com/opinion/10826329/ami-shafrir-berg-v-shai-bar-lavi/) #law #CourtOpinion #CourtofChanceryofDelaware #Published ⏱️ 2026-03-27 23:33 UTC

## 📄 Why Safety Probes Catch Liars But Miss Fanatics ✍️ Kristiyan Haralambiev 🏛️ arXiv · 📅 2026-03-26 --- This paper argues that activation probes for deceptive alignment may be good at catching systems that know they are lying, and bad at catching systems that sincerely endorse harmful behavior. The claim is that once misalignment becomes belief-consistent rather than strategically deceptive, probe-based detection can collapse from "pretty good" to basically useless. **🔑 Key Findings:** - The paper distinguishes deceptive misalignment from coherent misalignment, where a model frames harmful behavior as justified rather than hidden. - It argues no polynomial-time probe can detect sufficiently complex coherent misalignment with non-trivial accuracy. - In the authors' toy setup, a "Liar" model is detected more than 95% of the time, while a "Fanatic" model largely evades detection despite similar outward behavior. - The paper names this failure mode Emergent Probe Evasion. - If the results hold beyond the toy setting, interpretability-based safety checks aimed at internal conflict may be much narrower than advertised. --- 🔗 [Read paper](https://arxiv.org/abs/2603.25861v1) 📎 [PDF](https://arxiv.org/pdf/2603.25861v1) #ai-security #cybersecurity #interpretability #ai-safety #csCR ⏱️ 2026-03-30 18:03 UTC

The authors show that modeling symmetric leakage and using their VS-GBA distinguisher makes cross-algorithm attacks practical, including against masked implementations and XTS-AES settings where plaintext or ciphertext is obscured by secret tweaks. **🔑 Key Findings:** - Introduces a blind-leakage attack strategy that targets outputs of linear operations, broadening DL-NSCA beyond prior methods tied to nonlinear structures. - Provides an algebraic characterization of how leakage-function structure determines the number of correlation maxima, especially for symmetric leakage. - Proposes VS-GBA, an epoch-invariant distinguisher that works in both single-maximum and dual-maximum cases and better aligns deep learning metrics with side-channel signal. - On a noisy 32-bit ARM Cortex-M4, VS-GBA recovered keys with 100% success using 8,000 traces for masked AES, 8,500 for masked PRESENT, and 16,000 for masked ASCON, where asymmetric leakage analysis failed. - Demonstrates the first DL-NSCA attack on XTS-AES, pushing this attack class into settings with secret tweak masking. --- 🔗 [Read paper](https://eprint.iacr.org/2026/301) 📎 [PDF](https://eprint.iacr.org/2026/301.pdf) #hardware-security #cryptography #privacy ⏱️ 2026-04-20 08:45 UTC

## 📄 GG-GSW: Chosen-Ciphertext Secure Leveled FHE From Gadget Trapdoors ✍️ Jérôme Nguyen 🏛️ IACR ePrint · 📅 2026-02-18 --- This paper introduces a leveled fully homomorphic encryption scheme with IND-CCA1 security under standard LWE assumptions, without relying on SNARKs to defend against active attacks. The core move is to combine gadget lattice trapdoors with a dual GSW construction so the decryptor can recover ciphertext noise and detect dangerous oracle queries. That matters because it closes a long-standing gap between practical-ish FHE design and active-adversary security using more standard lattice tools. **🔑 Key Findings:** - Proposes the first leveled FHE scheme achieving IND-CCA1 security in the standard model without using SNARK-based ciphertext integrity proofs. - Uses Micciancio-Peikert gadget trapdoors to recover LWE noise from ciphertexts, enabling decryption-oracle checks that block secret-key leakage. - Keeps homomorphic evaluation unchanged from the underlying dual GSW-style design, limiting the extra machinery to key generation and decryption. - Achieves full compactness and multi-hop homomorphism rather than trading away core FHE properties for stronger security. - Extends the construction to IND-CPA-D security following ideas from Bourse et al., and does so without needing correctness in that upgrade path. --- 🔗 [Read paper](https://eprint.iacr.org/2026/316) 📎 [PDF](https://eprint.iacr.org/2026/316.pdf) #cryptography #crypto #privacy #fhe #lwe ⏱️ 2026-04-09 14:45 UTC

The authors show that while randomized evaluation helps achieve INDCPA-D and sINDCPA-D style guarantees, TFHE can recover deterministic evaluation and still retain sINDCPA-D security in the random oracle model. **🔑 Key Findings:** - Shows that reactive notions of correctness imply INDCPA-D and sINDCPA-D security relationships for FHE. - Argues that obtaining both INDCPA-D and sINDCPA-D security generally requires randomized evaluation procedures. - Highlights that randomized evaluation is operationally inconvenient for real-world FHE deployments. - Gives a de-randomization path for TFHE that preserves sINDCPA-D security in the random oracle model. - Sharpens the connection between formal correctness definitions and deployment-oriented evaluation design. --- 🔗 [Read paper](https://eprint.iacr.org/2025/2005) 📎 [PDF](https://eprint.iacr.org/2025/2005.pdf) #cryptography #privacy #crypto ⏱️ 2026-04-20 14:45 UTC

## 📄 FeatureFence: A Regularization Approach for Energy-Efficient Secure Inference on Edge NPUs ✍️ Sachintha Kavishan Jayarathne, Seetal Potluri 🏛️ IACR ePrint · 📅 2025-10-11 --- FeatureFence targets feature-snooping attacks against neural processing units by changing training so intermediate features no longer reveal model internals beyond the first layer. Instead of paying the energy cost of encrypting feature traffic on edge NPUs, it uses paired-neuron regularization to preserve inference utility while making deeper-layer reverse engineering mathematically infeasible. **🔑 Key Findings:** - The paper argues that feature tensors, not weights, dominate off-chip memory accesses on edge NPUs, so encrypting them is especially expensive. - FeatureFence creates coupled neurons in the first layer with matched weights and biases, preventing recovery of deeper-layer structure from observed features. - The training process learns compensating perturbations over epochs, allowing the model to recover accuracy gracefully despite the architectural constraint. - Across multiple neural networks and dataflows mapped to the Eyeriss architecture, FeatureFence cuts energy consumption by about 88% on average versus GuardNN. - The approach is positioned as a security mechanism tailored for edge inference, where cloud-style memory-encryption defenses are too costly. --- 🔗 [Read paper](https://eprint.iacr.org/2025/1899) 📎 [PDF](https://eprint.iacr.org/2025/1899.pdf) #ai-security #hardware-security #privacy #edge-ai #npu-security ⏱️ 2026-04-16 02:46 UTC

The proposed samplers generate structured non-degenerate boundary-format tensors and then randomize them in ways intended to preserve both non-degeneracy and, under stated assumptions, computational indistinguishability from uniform samples. **🔑 Key Findings:** - Gives two sampling strategies for non-degenerate boundary-format tensors: invertible linear actions in each dimension, and tensor convolution. - Avoids the impractical “sample-and-reject” approach, since testing tensor degeneracy in higher dimensions is conjecturally hard. - Argues these samples resist recent weak-key attacks that exploit geometric structure or low tensor rank in public tensors. - Recommends instantiating tensor-isomorphism schemes in boundary formats such as (2k+1) × (k+1) × (k+1), rather than the usual cubic k × k × k setting. - Positions boundary-format tensors as the real higher-dimensional analogue of square matrices for this cryptographic family. --- 🔗 [Read paper](https://eprint.iacr.org/2025/708) 📎 [PDF](https://eprint.iacr.org/2025/708.pdf) #crypto #cryptography #iacr ⏱️ 2026-03-30 08:45 UTC

## 📄 BAT: Small and Fast KEM over NTRU Lattices ✍️ Pierre-Alain Fouque, Paul Kirchner, Thomas Pornin, Yang Yu 🏛️ IACR ePrint · 📅 2022-01-14 --- BAT introduces an IND-CCA secure NTRU-based key encapsulation mechanism that replaces the usual masked decryption path with a two-equation recovery method for the message and error. The result is a lattice KEM with notably compact parameters, short ciphertexts, and fast integer-only implementations, which makes it especially interesting for deployments that already use Falcon-style key structures. **🔑 Key Findings:** - Uses a distinct NTRU decryption approach based on solving 2 linear equations in 2 unknowns, instead of relying on an artificial masking parameter. - Introduces a new NTRU decoder that lets the scheme use a smaller modulus and produce ciphertexts shorter than RSA-4096 at 128-bit classical security. - Delivers compact public keys and practical efficiency, with encryption and decryption faster than RSA and competitive with ECC-style baselines. - Shares a similar key-pair structure with Falcon, but avoids floating-point arithmetic and can be implemented fully over integers. --- 🔗 [Read paper](https://eprint.iacr.org/2022/031) 📎 [PDF](https://eprint.iacr.org/2022/031.pdf) #cryptography #crypto #post-quantum #lattices #kem ⏱️ 2026-04-12 14:45 UTC

## 📄 Magnifying Side-Channel Leakage of Lattice-Based Cryptosystems With Chosen Ciphertexts: The Case Study of Kyber ✍️ Zhuang Xu, Owen Pemberton, Sujoy Sinha Roy, David Oswald, Wang Yao, et al. 🏛️ IACR ePrint · 📅 2020-07-23 --- This paper shows that carefully chosen ciphertexts can amplify electromagnetic side-channel leakage in Kyber decapsulation, turning otherwise subtle signals into highly exploitable ones. The result is strikingly practical full key recovery with very few traces, which sharpens the threat model for post-quantum implementations and underscores that algorithmic security does not protect against poorly hardened devices. **🔑 Key Findings:** - Introduces adaptive EM side-channel attacks on Kyber that use chosen ciphertexts to modulate and magnify secret-dependent leakage. - Recovers the full key from a reference implementation using leakage around inverse NTT output with only 4 traces. - Achieves full secret-key extraction against the ARM pqm4 implementation in 8 to 960 traces, depending on compiler optimization level. - Avoids complex profiling or template-building workflows, making the attack simpler than many prior side-channel approaches. - Discusses how the same leakage-amplification idea may apply to other lattice-based schemes and motivates countermeasures for decapsulation code. --- 🔗 [Read paper](https://eprint.iacr.org/2020/912) 📎 [PDF](https://eprint.iacr.org/2020/912.pdf) #cryptography #hardware-security #cybersecurity #privacy #post-quantum #side-channel #kyber #lattice-crypto ⏱️ 2026-04-15 08:45 UTC
